About Project

The intensive cultivation of high yielding modern crop varieties, in the past few decades’ increased the crop productivity. However, this has resulted into emergence of micro and secondary nutrients deficiency in most of the soils, causing reduction in yields. In order to delineate the micro and secondary nutrient deficient areas and to alleviate the nutrition stresses, the Indian Council of Agricultural Research initiated the All India Coordinated Scheme of Micronutrient in Soil and Plants in 1967.

There are sixteen cooperative and five voluntary centers of this project in the country. A centre for Maharashtra state was initiated at Dr. PDKV, Akola in 1996.

The deficiencies of secondary and micronutrients and toxicities of heavy metal elements were subsequently noticed in many parts of the country. In view of this, the project mandate was expanded. The name of the project was modified to All India Coordinated Project of Micro and Secondary Nutrients and Pollutant Elements in Soils and Plants.

The Coordinating unit is functioning at Indian Institute of Soil Science, Bhopal. The centre at Lucknow is involved mainly in physiological research on micronutrient nutrition of plants while the remaining 19 centres concentrate their researches on the micro and secondary nutrient and pollutant elements in soils and plants.

Jurisdiction of the project

Maharashtra State represents four major regions viz; Vidarbha, Marathawada, Western Maharashtra and Konkan and there are four agricultural universities in these regions. Indian Council of Agricultural Research, has given the centre of “All India Coordinated Research Project on Micro and Secondary Nutrients and Pollutant Elements in Soils and Plants” at Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola to carry out the research work  on micro, secondary and pollutant elements in soils and plants in the Maharashtra state.

Agro Climatic Conditions

The state has humid to per humid type climate in Konkan and western ghats, semiarid type in central and western Maharashtra, while sub-humid type in eastern part of the state. The annual rainfall in the state varies from 450 mm in the rain shadow area to 6000 mm in western ghats of which 80 per cent is received from June to September. Konkan and western ghat region has a water surplus limited to June to October with growing period of more than 210 days. While rain shadow areas of western and central Maharashtra have very few months of water surplus with growing period of 90 to 150 days. In eastern part of the state, the growing period ranges from 150 to 180 days. The state is divided into six agro – eco regions which in turn are sub divided in to twelve agro – ecological sub regions.

 

Soils
The geological formations in the state include Deccan trap, Lameta beds, Gondwanas and Vindhyan system. Physiographically, the state is divided in to three broad regions viz, western Konkan coast, Western Ghats and North Deccan plateau. The soils occurring on each landform are characterized during the soil resource mapping of the state. Taxonomically the soils of Maharashtra are categorized into five soil orders namely Entisols (36.71 %), Inceptisols (30.9 %), Vertisols (26.3 %), Alfisols (5.6 %) and Mollisols (0.1 %) which are sub divided into 8 sub orders, 9 great groups, 19 subgroups and 356 family associations.

Problems in micro and secondary nutrients

Deficiencies of micronutrients drastically influence the growth, metabolism and reproduction phase in plants, animals and human beings. Widespread deficiencies of some micronutrients have been observed in the soil.

The high yielding varieties/hybrids of cereals, oilseed, pulses, cotton, sugarcane, vegetable and horticultural crops etc grown since 4-5 decades using chemical fertilizers without or less supplementation with organic manure led to deficiency of micro (Zn, Fe, B,) and secondary nutrients (S) in the soil. Besides this, higher crop yields which increase plant nutrient demands, use of high analysis NPK fertilizers, reduced use of organic manures on many agricultural soils and imbalance use of major nutrients are some of the reasons for micronutrient deficiencies. This has resulted into decreased nutrient use efficiency of major nutrients (N, P and K).

For sustaining the crop productivity, increasing nutrient use efficiency and maintaining soil quality in long run judicious use of micronutrients through organic manures is the urgent need of time.
